Chip is right about having lots of time. I made a lot of mistakes in my first try, mostly didn't sqeegee enough, because I thought I had to move really fast. I ended up with a lot of epoxy under the glass. How do I know that? Let me count the ripples...... I found that going over and over with the sqeegee worked best. I found a really flexible 2 inch wide plastic squeegee at an autobody supply store. Squeegeeing worked best with the sqeegee at about a 45 degree angle to the surface.

Space heater---make sure it is electric. Combustion types put out fumes that interfere with the epoxy bonding and varnishing. There are quite a few threads about this.
